There may be provided a connector for a liquid container. The connector may include a connector body, and a through-hole for fitting on a neck portion of the liquid container. The connector may further include a restraining arrangement positioned proximal to the through-hole. The restraining arrangement may include a first restraining member and a second restraining member extending towards a central axis of the connector body. The first restraining member may have a distal end that extends further than a distal end of the second restraining member. The distal end of the first restraining member may engage the neck portion of the liquid container at a first position, and the distal end of the second restraining member may engage the neck portion of the liquid container at a second position. The connector may further include a connector-to-key-interface arrangement configured to mate with a corresponding surface of a key member.
